Seems clear enough. It just means I now have to stop putting off learning how to use I2C communications.

Arduino Dock Serial Communication
I know that the main communications between the Omega and the Arduino is through I2C. This is actually a pretty slick way of doing it. However, sometimes, I just want something quick and dirty to get output from the Arduino - serial communications.
While combing through the community forums, I found small references to using the screen command, and how the Omega is supposed to be connected to the Arduino serial pins 0 and 1. I tried to use both screen and minicom to communicate to /dev/ATH0 and /dev/ttyS0. ATH0 gives me a blank screen with no output. ttyS0 outright fails (as I think I should expect).
Is there something I'm missing? Is I2C currently the only cross-board communication option?
